Dna

Contains the genetic information of the cell.

Chromosomal

Carries the genetic information that is essential to a cell.Typically a single, circular, double-stranded DNA molecule.

Plasmid

Carries genetic information that may be advantageous to a cell in certain situations.

Endospore

A type of dormant cell that is extraordinarily resistant to damaging conditions including heat, desiccation, ultraviolet light, and toxic chemicals.

Gas vesicles

Small, rigid structures that provides buoyancy to a cell.

Granules

Accumulations of high molecular weight polymers, which are synthesized from a nutrient that a cell has in relative excess.

Ribosomes

Intimately involved in protein synthesis.Two subunits, 30S and 50S, join to form the 70S ribosome, which serves as the structure that facilitates the joining of amino acids.
